All wiring must comply with local electrical codes and
ordinances or as specified on installation wiring diagrams.
Wall module wiring can be sized from 16 to 22 AWG (1.5
to 0.34 mm
), depending on the application. The maximum
length of wire from a device to a wall module is 1000 ft
(305 m). Twisted-pair wire is recommended for wire runs
longer than 100 ft (30.5 m).
The cover of the wall module is fixed in place using a tab
located on the underside of the unit; to disassemble the
cover and the subbase, see Fig. 1.

Table 1. Features of T7460 Versions
Setpoint Bypass/ LED Fan speed
The T7460B,C,D,E,F packages include two setpoint dials.
By default, the "Celsius Relative" type is mounted. This can
be easily replaced with the "Celsius Absolute" type by
pulling the one dial off and inserting the other one.

Mount the T7460A,B,C,D,E,F Wall Modules on an inside
wall approximately 54 in. (1.3 m) from the floor (or in the
specified location) to allow exposure to the average zone
NOTE: Maintain a mounting clearance of approx. 4 in.
(10 cm) to the left-hand side of the module in
order to allow a free airflow for the temperature
sensor and accessibility of the setpoint dial.
Do not mount the wall modules on an outside
wall, on a wall containing water pipes, or near air
ducts. Avoid locations that are exposed to
discharge air from registers or radiation from
lights, appliances, or the sun.
The T7460D,E,F should not be connected to
controllers that do not support fan operation
(e.g. W7751, W7762, W7763).
Keep wiring at least one ft (305 mm) away from
large inductive loads such as motors, line starters,
lighting ballasts, and large power distribution
Run wall module wiring separately from 50 Vac or
greater power wiring.
The wall modules can be mounted on a 60-mm wall outlet
box using No. 6 (3.5-mm) screws or on a wall (see Fig. 2
and 5). When mounting directly on a wall, use the type of
screws appropriate for the wall material.
